It’s finally here: the official teaser trailer for “The Dark Knight Rises.” Okay, so it’s mildly disappointing considering the fact that it’s mostly footage from the other movies, and we only get a few seconds to glimpse at Batman and Bane. But, it’s the epic conclusion to the Dark Knight legend! It will be in IMAX!

Trailers give fans that much-needed glimpse into that film that we’re dying to see and help fight off the starvation for the real film. Here’s some of the best trailers to hit YouTube that helped quench fans thirst until the movies hit theaters.

There was fanmade trailer for “The Dark Knight Rises” that was so convincing that it even tricked some of our staff -- even though Bane’s voice was portrayed by Robin Williams.

Who could forget the trailer for “Harry Potter and the Deathly Hallows: Part II,” the other epic conclusion of a saga?

The trailer for “Sucker Punch” got everyone excited. Too bad the movie didn’t match the hype. At least we have this to watch, and we don’t have to shell out money to watch this piece of trash.

This isn’t the official “Green Lantern” trailer, but a fan-created vision staring Nathan Fillion as Hal Jordan. We’re still wishing this was the real movie instead of the monstrosity that just came out in theaters.
